Domain, Boundary, Edge, Point, and Pair Nodes for the Multibody Dynamics Interface
The Multibody Dynamics Interface has these domain, boundary, edge, point, and pair nodes (and subnodes), listed in alphabetical order, available from the Physics ribbon toolbar (Windows users), Physics context menu (Mac or Linux users), or by right-clicking then main physics interface node to access the context menu (all users).
In general, to add a node, go to the Physics toolbar, no matter what operating system you are using. Subnodes are available by clicking the parent node and selecting it from the Attributes menu.
In the COMSOL Multiphysics Reference Manual see Table 2-4 for links to common sections and Table 2-5 to common feature nodes. You can also search for information: press F1 to open the Help window or Ctrl+F1 to open the Documentation window.
The links to the nodes described in external guides, such as the Structural Mechanics Module User’s Guide, do not work in the PDF, only from the online help in COMSOL Multiphysics.
Features Available from Submenus
Many features for the Multibody Dynamics interface are added from submenus in the Physics toolbar groups or context menu (when you right-click the node). The submenu name is the same in both cases.
The submenus at the Domain level are Gears; Volume Forces; Mass, Spring, and Damper; Domain Constraints; and More.
There are also the Edges and Points submenus.
The submenus at the Global level are Joints, Gear Pairs, and Variables.
Right-click the Multibody Dynamics node, select from the Joints menu (if No Sorting is selected from the context menu) or the Global>Joints menu (if Sorting by Space Dimension is selected).
The Attachment node is available from the Physics toolbar, Boundaries menu.
